Looking again, they're not

Looking again, they're not the tibia, but an adaptation of the tarsi..?

Thank you

Hi Richard,
Thank you for your help, and the invaluable data.

Interestingly I do have a silver birch in my front garden. Would that make it good for Croesus septentrionalis, or would that be wishful thinking?

Croesus septentrionalis

How about this, Croesus septentrionalis, the thought did cross my mind re the larva on my hazel tree. Was I surprised when I Googled it and came up with my image showing the larvae of, yep as you have already seen, Croesus septentrionalis. Done and dusted would you say, or am being a bit over zealous?

That same image can be found here on iSpot.
